Figure 4.

Comparison of biomass concentrations (X) and consumption of oxygen per methanol (Yo/m)
in two similar TLFB processes (filled symbols, solid lines) and in two similar MLFB
processes at 30°C (open symbols, dotted lines). The methanol phase is divided in temperature
limitation and methanol limitation only in the TLFB process. Both types of processes
were controlled at DOT = 25% with similar oxygen transfer rate (stirrer speed and
aeration rate in the same bioreactor).
